EDGAR SI-IANIZ, OF ROCHESTER, NEW YORK.

BUTTON-MAKING MACHINE.

T 0 all whom it may concern Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Button -Making Machine, of which the following is a specification.

My invention has for its object the production of a button-making machine, which is particularly simple in construction, and highly efficient in use; and to this end it consists in the novel combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Serial No. 350,722.

pressing a button blank against the under face of the mold so that a recess 4, opening out through the under face of the blank, will be registered with the part of the mold cavity opening out through the lower face of the mold, whereby during the casting operation this recess will form substantially an uninterrupted continuation of the mold cavity.

The invention includes further a mold formed of two sections and means for automatically moving the sections generally in opposite directionsso as to open and close the mold and move the same into and out of registration with the reservoir, and means for operating in regular sequence therewith the valve of the reservoir and the buttonblank support. a

As illustrated, the support 1 for the button-head, and the mold 2 are movable as one body relatively to the reservoir 3, and the support is movable relatively to themold, the mold being interposed between the reservoir and the support 1 and normally spaced apart therefrom. Said mold is formed with inlet and exit orifices 5 and 6 on opposite sides thereof, serving to register, respectively, with the exit port 7 of the reservoir and the recess 4 of the button-head on the support, and being normally out of registration therewith.

As will be understood by those skilled in the metal casting art, the shape of the shank will conform to the contour of the mold cavity, which may be of any desired shape. In the particular dies, or molds, illustrated in the drawings, the mold cavity is of substantially ring shape and is provided at opposite sides thereof with radial continuations, or ports 5 and 6, leading through the upper and lower faces of themold, respectively. This form of cavity will provide a shank having a transverse opening, or eye. As will be obvious, however, should it be desired to cast a non-eyelcted shank, the central projection, or core 2", would be eliminated, and if it were desired to cast a cyclical shank, the cavity in each die section would be made semi-cylindrical. The particular shape of the mold cavity has no effect upon the operation of the machine or parts thereof.

Preferably, the support for the buttonhead and the mold are movable vertically, the mold being arranged above the support and the reservoir above the mold, so that the molten material may feed by gravity from the reservoir into and through the mold, and into the recess of the button-head. Said support 1 is provided with suitable means for frictionally holding the button-head with its recess presented outwardly so that when a shank has been cast thereon the movement of the support from the mold will remove the button-head with shank attached from the support, said means being formed with a socket 8 for receiving the buttonhead, and with a stud 9 for entering an opening provided in the main body of the support 1. Preferably the mold 2 is composed of two sections which are movable toward each other as they are carried upwardly toward the reservoir, andaway from each other as they are moved away from the reservoir after the casting operation, by means hereinafter described. Strippers 10 are provided for detaching the shank with button-head attached from the mold after the sections of the mold have been separated.

In the illustrated embodiment of this invention, the support for the button-head, the mold and reservoir are supported by a frame comprising a hollow base 11, a hollow upright, or standard 12 rising from the rear portion of the base and formed with a guide consisting of ways 13 spaced apart on its front face, and a bracket 1-1 fixed to the upper end of the standard 12 and overhanging the front portion of the base; and the mold-sections and the support for the button-head are supported by a carriage 15' movable along tne vertical. guide or ways 13, and the reservoir depends fro-m the overhanging bracket. Said carriage is formed with a vertical tubular guide 16 in which the support 1 for the button-head is movable, and with transverse horizontal ways 17 in which slides 18, which support the moldsections, are movable, and also with a boss 19 to which the strippers 10 are attached. The support 1 projects through the top of the base 11, and is held in its starting position by aspring 20 encircling the lower portion thereof and bearing against the lower face of the carriage and a foot 21 at the lower end of said support. Said slides 18 are movable along the transverse ways 17 to bring together and separate the mold-sections, by a cam-plate 22 arranged at the rear of the carriage between the ways 13, and formed with upwardly converging grooves 23 which receive rearwardly-extending engaging arms 24L provided on the slides, said grooves widening gradually teward their upper ends. The engaging arms 21 extend through horizontal slots 25 formed in the carriage. Said cam-plate 22 is adjustable by a lever 26 arranged within the hollow standard 12, and pivoted at one end to said standard, and connected intermediate of its ends to the plate 22 by a pivot 27 extending through a slot 28 formed in th standard, and saidcam-plate 22 is acid in position by bolts 29.

is seen in Fig. 5 the moldsections are detachablv secured to the slides and are here illustrated as provided with stems 30 an ranged in passages provided in the slides, and as adjustable by hollow screws 31 abutting against the ends of the stems 30. Set screws hold the mold-sections and the adjusting screws in their properpositions. Scrapers 33 supported by the carriage are provided for removing anyspilled metal from the upper faces of the mold-sections, and for also engaging the spur formed at the upper end of the shank of the button by the inlet orifice 5, and facilitating the removal of the shank with button-head attached, from the mold.

The reservoir 3 is inverted cone-shaped, and the lower end thereof is closed by a plug 34,- in which the exit-port 7 is formed. This port is opened and closed by a plunger 35,

actuated by means, here nafter described, to v open the port when the inlet orifice 5 of the mold is in registration with the exit port 7 of the reservoir. Said means operates to permit the return of the plunger to its normal position to close the port before the return of the mold to its starting position. As shown, the plunger 35 is carried by an .rm 36 mounted on a rod 37 movable vertically through the hollow standard 12, said rod projecting into the hollow base 11. Said plunger 35 is also provided with suitable means for turning and preventing the same from becoming set, as a gear 38 meslr ing with a pinion 89 on the plunger, and having a handle 1-0 projecting beyond the periphery of the reservoir. The reservoir may be heated by any suitable means, here shown as a hollow ring-shaped burner 11 connected by a pipe 42 to a suitable fuel supply, not shown, and provided with jets -13 directed toward the surface of the reservoir. Preferably the reservoir is surrounded by a jacket 44 which also incloses the burner, and is provided with circumferential corrugations 45 for increasing the area of its surface.

The means for controlling the operation of the plunger, carriage, and support for the button-head, comprises a prime mover in the form of a rocking element or shaft 46, and cams 4:7, 4:8 and d9 mounted on said element for moving, respectively, the plunger, carriage and support for the button-head in one direction. A spring acting on the rod 37 returns the plunger to its original position. The carriage returns by gravity to its original position, and the spring 20 returns the support for the button-head to its starting position. The rocking element 46, as here shown, is journaled in the base 11 and extends from front to rear thereof. The

cams l7 and 418 are preferably scroll-cams fixed on the shaft 46 and rotatable therewith. The cam 19 is loosely mounted on the shaft -16 and is practically a crank having a roller for engaging the foot 21. of the support 1. A spring 51 encircling the shaft 46 and having one end connected to the cam 49, and its other end to said shaft transmits the motion from the shaft to the cam 49, when no work is being done by the cam 49 by reason of the carriage being moved upwardly by the cam 18. When the carriage has reached the limit of its upward movement and is being held in such position by the high surface 52 of the cam 18, the spring 51 is tensioned by further movement of the shaft 46 and raises the support 1 in its guide 16 against the spring 90. The shaft 416 is initially actuated by any suitable means in one direction, as a sprocket wheel 53, connected to a treadle, not shown, by a chain 54, and in the reverse direction by a spring encircling said shaft and having one end connected to the base 11, and its other end to the shaft. When the shaft 46 is rocked in one direction by depressing the treadle, the spring 55 will be tensioned, so that the shaft 46 will be returned to its starting position by said spring as soon as pressure is removed from the sprocket wheel The return movement of the shaft by the spring 55 is practically instantanemls, so that the plunger may return to close the exit port 7 of the reservoir before the mold has been moved by the carriage away from the reservoir. An unattached part 56 movable reciprocally in a guide 57 formed in the top of the base, transmits motion from the cam 48 to the carriage. said part having a lengthwise adjustment, here shown as ef fected by a movable shoulder or nut 58 at its upper end. Upon the return of the shaft -16 to its initial position. the roller 59 at the lower end of the part 56 is engaged by the radial face of the cam 48 and limits the movement of the shaft 46. The return of the shaft 46 to its original position under the influence of the spring 555 permits the cam 49 to return to its starting position under the influence of the spring 51 and thus permits the support 7 for the button-head to be withdrawn from the mold by the spring 20, leaving the shank with buttonhead attached supported by the mold. Durthe movement of the carriage by gravity, the mold-sections will be separated, as previously described, and the strippers 10 will remove the shank with button-head attached from the mold and. permit the same to fall upon the chutes 59 by which they are conveyed to any suitable receptacle.

As will be understood, the parts of the machine move in a cycle or in regular sequence, and are operated from a single prime mover. Each part has a definite initial position, or position of rest, to which it returns, at the end of each complete cycle of operation. The prime mover is the shaft 46, rocked in one direction by pressure on a treadle and returned to its initial position by a spring 5:"). As described, the mold, or die, is formed of two sections, each carried by a slide 18 occupying, when unrestrained, its lowermost position, in which the die sections are held widelv separated and out of registration with the reservoir outlet. The slides 18 are guided by the horizontal ways 17 on the carriage 15, which is vertically movable and is guided by the ways 13. The cam plate 22 is hel d in a fixed position on the front face of the standard 12 and directly in the rear of the carriage 15, and the groove or slot 23 thereof receives the arms, or projections 24-, extending rearwardly from the slides and through the horizontal slot 25 in the carriage 15. On the for 'ard rocking of the shaft 46, the cam 18 thereof, moves the carriage 15 upward toward the metal reservoir, and in this movement the projections cooperate with the upper walls of the groove 23 and force the slides 18 toward each other,

thus bringing the dies, or mold sections, to-

gether and in proper registration with the reservoir outlet. on the return movement of the shaft 46, the carriage 15 drops down and the projections 24 then coact with the lower uills of the groove for forcing the slides 18 back to their initial positions and thereby separating the die, or mold sections, and moving the same out of registration with the reservoir outlet.
